(54) DEVICE TO REMOVE DUST FROM A SPREADED SURFACE

one

The invention relates to devices designed to remove dust from the electrified surfaces of the powder removal devices.

A device for removing dust from an electrified surface is known, which contains a cleaning element and a container for collecting dust 1 located beneath it.

This device does not provide sufficient cleaning efficiency due to only a mechanical effect on the surface being cleaned.

The purpose of the invention is to increase the cleaning efficiency.

This goal is achieved by the fact that in a device for removing dust from an electrified surface containing a cleaning element and a container for collecting dust below it, the cleaning element is an endless drive belt located parallel to the surface being cleaned and grounded electrodes and brushes mounted on the tape the number of electrodes, while the brushes are attached to the electrodes in the direction of the belt, and the dust collection container is mounted on a frame made of conductive material.

FIG. 1 shows the proposed device, side view; in fig. 2 is a schematic representation of the interaction of electric fields arising on the details of the device, top view.

5 A device for removing dust from an electrified surface contains a cleaning element, which is a drive endless belt 1 located parallel to the surface to be cleaned 2 (in this case, a disk), mounted on a belt 1

t grounded electrodes 3 and .brushes 4 by the number of electrodes 3, and a dust collecting container 5 located under the cleaning element. The brushes 4 are attached to the electrodes 3 in the direction of movement of the tape 1. The endless tape I is mounted on the pins 6 and 7. The container 5 for collecting dust is mounted on the frame 8 made of conductive material. The pulley 6, the container 5 and the block 9 of the electrifying brushes are fixed on the bracket 10. The grounding of the electrodes 3 is provided by the wire 1C st. with the edge of the tape 1.

The device works as follows.

By rotating the disk 2 in the direction indicated in FIG. 1 by the arrow, pulley 7 receives a rotation of the same direction. Moving with this tape 1 is attached to it grounded electrodes 3 (Fig. 2). The grounding of the electrodes 3 provides the wire 11, which constantly touches the surfaces of the conductive pulleys 6 and 7. If, when the device operates on the surfaces of the disk 2, electric charges of a positive sign are generated, then under the action of the electric field created by them, the electrodes 3 become the negative electrodes of a kind of capacitor whose positive electrode is the surface of the disc 2 to be cleaned. Dust deposited on the surface of disc 2 (schematically depicted as a circle) when electrode 3 approaches it. begins to re-electrify and tends to come off the charged surface of the disk 2. In case of re-electrification of dust, the holding forces between the dust and the surface of the disk 1 decrease, and this justifies the possibility of transporting the collected dust from the surface of the disk 2 to the dust collector 5 by brushes 4 and electrodes 3, and if the surface of the disk 2 is positive, then dust has a negative charge. Fine dust remains behind the electrode 3, due to the influence of electrical forces not yet lost contact with the disk 2, which is swept away with a brush 4. 8 container 5 under the action of an electric field created positively ktrizovannym disc 2, electrified negative charges creates a negative electric field. The electric field lines in the middle of the frame 8 are concentric. When two negative electric fields of the same name interact - the floor created by frame 8, and the floor created by a speck of dust, the speck of dust repels itself from the walls of frame 8 and moves to the center. Gravitational forces also act on the dust particle, as a result of which the dust particle is directed to container 5. The proposed device allows one to completely remove dust from electrified surfaces due to mechanical action and due to the action of an electric field generated by the electrodes of the cleaning element. DETAILED DESCRIPTION OF THE INVENTION A device for removing dust from an electrified surface, comprising a cleaning element and a container for collecting dust located under it, characterized in that, in order to increase the cleaning efficiency, the cleaning element is an endless drive belt disposed parallel to the surface being cleaned and mounted on the tape is grounded electrodes and brushes according to the number of electrodes, while the brushes are attached to the electrodes in the direction of the belt, and the dust collection container is mounted on the frame, in Made of conductive material.
